ABSTRACT:
A process for isolating a phosphatidylcholine from vegetable lipid mixtures wherein the lipid mixture is dissolved in a solvent mixture of a low boiling petroleum ether fraction (40.degree.-80.degree. C.), a lower C.sub.1 -C.sub.4 -alkanol and water, the solution is introduced into a column filled with silica gel at a temperature in the range of 20.degree. to 50.degree. C., the elution is carried out at that temperature with the same solvent mixture and the main run is collected and a pure phosphatidylcholine free of other phospholipids present in the starting vegetable lipid mixture is isolated therefrom in a usual manner.
